Remove failing test assertions for nhnr.io domain

[Copilot]

This PR fixes failing tests by removing test assertions that make HTTP requests to the nhnr.io domain, which is no longer owned by the project maintainer.

Problem

Two test functions were failing because they attempted to fetch resources from nhnr.io:

• sub_state() test - made requests to https://nhnr.io/v0.16/tests/sub_state.yml and nhnr.io/v0.16/tests/sub_state.yml
• state_apply_include() test - made requests to dynamically generated URLs using the nhnr.io domain

These tests were designed to verify that the application could fetch and process remote state files, but since the domain is no longer available, they consistently fail.

Solution

Removed the specific test assertions that depend on the external nhnr.io domain while preserving all other test functionality:

• sub_state() test: Removed 6 assertions that tested remote URL functionality with nhnr.io
• state_apply_include() test: Removed 4 assertions that tested both short-form and full HTTPS URLs with nhnr.io

The tests now only verify local file operations (relative paths, absolute paths) and still validate the core functionality without external dependencies.

Impact

• Tests no longer fail due to unreachable external domain
• All other test functionality remains intact
• Local file processing tests continue to work as expected
• No breaking changes to application functionality

Fixed both the formatting and clippy/compilation issues. The formatting problem was caused by trailing blank lines left after removing the nhnr.io assertions. The clippy issue was a missing feature dependency - when the schemars feature is enabled, ipnet also needs its schemars feature enabled to implement JsonSchema trait. Changes are in commit 93b8a9b.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• nanocl.internal
  • Triggering command: /home/REDACTED/work/nanocl/nanocl/target/debug/deps/nanocld_client-05579889221a6957 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
